How to write the Install and configure mail Service scripts

"Requirements":

Automatically complete installation postfix (enter host name, domain name and install path as prompted), Dovecot, SquirrelMail, basic configuration

"Hint":

This script continues as the installation of the lamp environment is complete (the Apache installation path is/usr/local/apache/and can be replaced with a different path by modifying the script start position httpd_dir variable value)

#!/bin/bash

Httpd_dir= "/usr/local/apache"
